[Q] Changing Mac Address - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hi, is there a way of changing the mac address of the s4 mini (gt-i9195)?
I am on Stock Rom 4.2.2 and tried some apps from the Play Store ( MacMan, Mac Address Ghost) but every time I change the Mac Address I can't connect to my router anymore. I always get "authentication error"

Backup your EFS. Next you can edit the file under efs which holds Mac adress info.
Not tried, just a suggestion
Edit: The file is "/efs/wifi/.mac.info" on my device.

thank you very much. It worked :good:

[Q] Change MAC address

Hi
I've got one problem. I was trying to change my MAC address on Samsung Galaxy S3 Mini. That operation was successful.
I changed it by commands
Code:
su
ip link set wlan0 ADDRESS 00:00:00:00:00:00
And I also tried app "MAC Spoofer" . Both successful. But after changing MAC address I can't connect to WiFi. There is a problem with authentication. So I was looking for a solution on XDA. I found it http://forum.xda-developers.com/showpost.php?p=51072203&postcount=214 but I don't understand it. Could anyone tell me what should I do step by step?
Regards,
maciek1235
P.S. I also checked that thread http://forum.xda-developers.com/showthread.php?t=917684 but it didn't work for me

Why stop it? Its a security feature that makes your device much harder to track down.

(Need "more" help) WIfi mac address still stuck to 02:00:00:00:00))

Hi,
I have read almost everything that this forum gave me and some solution from the rest of the internet and STILL my wifi mac address is still stcuk at 02:00:00:00:00:00
Wifi won't turn on and it won't display available wifi
I can't remember exactly what caused it but i'll try to share my recollection
I vaguely remember that i was able to connect to the wifi before trying to fix it. Can't recall what really happened
I fixed the random rebooting nexus 5x by using unblod fix
I think i tried rooting it and succeeded with a twrp recovery
I vaguely remember flashing a zip custom rom with wrong version and brought it into a soft brick. Cant find the file anymore.
I reflashed it with flash all batch file from stock firmware
the phone is bootlooping
Fixed it again using unblod exe using the stock firmware's boot.img
Wifi wont turn on
mac address is 02:00:00:00:00:00
Tried on android 6.0, 7.0, 7.1.2, 8.0 and 8.1.0
Other solutions tried:
Nil Mac app. Seems to work app wise but mac is still stuck at 02:00:00:00:00:00 on settings. Wifi wont turn on
Manually edited, placed *.bin file in /persist, and /etc/firmware/wlan/qca_cld/
WIfi mac changer apps from appstore (they dont work)
Some root apps that mess with the phone's setting (cant find anything that seems to deal with wifi mac address)
p.s.
I also tried bricking the phone using TWRP wipe and checking all the wipe locations to eliminate remnants from previous mods
I cant seem to do anything. Still stuck at 02:00:00:00:00:00
Any more suggestions on where to look?
Or is android not getting the real mac address and revert to 02:00:00:00:00:00 and wont let wifi turn on during flash all script?
Thanks in advance.
Recent Android hides the MAC address to prevent tracking. 02:xx:xx:xx:xx:xx means a site-local MAC address.
Try using "ip link" and looking for the wlan0 entry. eg.
Code:
22: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 3000
link/ether 2c:59:8a:xx:xx:xx brd ff:ff:ff:ff:ff:ff

HI,
thanks for the reply. I already did that and i got a mac address that is not 02:00:00...
then i tried to change it using if config just to see if it changes using the command.
I got an error saying wlan0 not found (not exact words)
Is there a different MAC address in Settings -> System -> About phone -> Status ?

Did this ever get fixed? I'm facing the same issue. However, the steps I did was trying to spoof a MacAddress using Busybox and a terminal emulator.
Just using that would not allow me to connect to wifi, but wifi was turned on. Then I read to change the wlan.bin file in the persists folder.
After I changed that file and did a reboot wifi would not turn on.
I tried:
1. factory reset
2.Changing the wlan.bin back to what it was
3.Sideload android 8.0
4.Flash OEM back to factory
Nothing seems to work. Settings->about->status MacAddress says "unavailable", but
wifi -> preferences -> advance shows MacAddress 02:00:00:00:00:00
Any help would be great,

Try AMC, its the only MAC Address Changer app I could find that worked on my 5x. That was without a screwed up MAC address to begin with, but It might work for you.
I downloaded it from the play store, but now its not there. Here's the apk from my phone:
https://sqerk.com/pythonlimited.amc.apk
Looks like AMC was forked from nMAC :

Thanks, but I figured it out. I was trying to flash with the same version 8.0...and for whatever reason that did not work, so I tried a costume ROM and it brought back my MAC address, so then I flash again to android 8.1 and my MAC address problems are fixed. Not sure why flashing with the same version did not fix it.
Thanks,

What Custom ROM did you use friend? I have the same exact issue with my Nexus 5. Maybe finding your previously installed Custom ROM, I can fix the issue too. I saw a lot of threads says that installing Custom ROMs or downgrading then upgrading OS using OTA updates given from their Android System fixed the issue. MAC address is important and controls everything that has to do with wireless connections in your device. Maybe this can help be fix my issue too. I am almost convinced to buy a brand new smartphone. It's almost my limit here... If this doesn't bother you, please, can you tell me what is the ROM you used?
